“‘Give it to me, for God’s sake!’ I said, and slipped the gun from his hand; and in the same instant there was a sound of running steps up the garden path, and immediately the flash of a bull’s-eye lantern upon the fan light over the front door.  Then the door was tried, and directly afterward there came a thunderous knocking, which told me a policeman had heard the shot.

“I went to the door, and opened it.  Fortunately the constable knew me, and when I had beckoned him in, I was able to explain matters in a very short time.  While doing this, Inspector Johnstone came up the path, having missed the officer, and seeing lights and the open door.  I told him as briefly as possible what had occurred, and did not mention the Child or the Woman; for it would have seem too fantastic for him to notice.  I showed him the queer, wet footprints and how they went toward the closed doors.  I explained quickly about the mats, and how that the one against the cellar door was flat, which showed the door had been opened.

“The inspector nodded, and told the constable to guard the door at the top of the cellar stairs.  He then asked the hall lamp to be lit, after which he took the policeman’s lantern, and led the way into the front room.  He paused with the door wide open, and threw the light all ’round; then he jumped into the room, and looked behind the door; there was no one there; but all over the polished oak floor, between the scattered rugs, went the marks of those horrible spreading footprints; and the room permeated with the horrible odor.

“The inspector searched the room carefully, and then went into the middle room, using the same precautions.  There was nothing in the middle room, or in the kitchen or pantry; but everywhere went the wet footmarks through all the rooms, showing plainly wherever there were woodwork or oilcloth; and always there was the smell.

“The inspector ceased from his search of the rooms, and spent a minute in trying whether the mats would really fall flat when the doors were open, or merely ruckle up in a way as to appear they had been untouched; but in each case, the mats fell flat, and remained so.

“‘Extraordinary!’ I heard Johnstone mutter to himself.  And then he went toward the cellar door.  He had inquired at first whether there were windows to the cellar, and when he learned there was no way out, except by the door, he had left this part of the search to the last.

“As Johnstone came up to the door, the policeman made a motion of salute, and said something in a low voice; and something in the tone made me flick my light across him.  I saw then that the man was very white, and he looked strange and bewildered.

“‘What?’ said Johnstone impatiently.  ‘Speak up!’

“’A woman come along ’ere, sir, and went through this ‘ere door,’ said the constable, clearly, but with a curious monotonous intonation that is sometimes heard from an unintelligent man.
